Description

Technical Field

[0001] The utility model belongs to the technical field of cable connectors, in particular to a cable connector structure. Background Art

[0002] With the rapid development of electronic devices, people have put forward higher requirements for computer operation, storage, computing and other capabilities. In particular, the requirements for server computing power and functions have led to the integration and specialization of various server components and modules.

[0003] Servers are primarily composed of components such as processors, hard drives, memory, and network cards. Similar to the basic architecture of common computers, servers must provide more reliable and stable services, so they require higher processing power, stability, reliability, security, scalability, and manageability. Cables are typically used to effectively transmit power and information between server modules. The primary function of cables is to transmit power, transmit signals, and convert electromagnetic energy. Different cables have different connection properties. Commonly used cables for servers include PWR power cables, MCIO cables, fiber optic cables, SAS cables, SFP (small form pluggable) optical module cables, twin-axial cables, serial cables, and AOC (active optical cables).

[0004] Due to the increasing requirements for the configuration and functions of independent modules, the demand for cables will increase, and the requirements for wiring within the server will also become increasingly stringent. If the male and female connectors are not properly snapped together, it will not only affect the electrical performance, but also the signal integrity, heat dissipation effect, and the stability of mechanical performance. The traditional snap-on design of the male and female connectors uses elastic press-on snaps, which use the bumps on the snaps to achieve reliable snap-on connection between the male and female ends of the connector. In actual use, manual wire management, wire stacking and squeezing, etc. may cause the elastic press-on snaps to fail to unlock or mislock, thereby separating the male and female ends of the connector, resulting in connection failure, causing server bandwidth loss or even downtime, and other failure anomalies, resulting in increased operation and maintenance costs. Utility Model Content

[0005] In order to solve the problem that the male and female ends of traditional connectors use elastic press-type buckles, manual wire management, wire stacking and squeezing, etc. may cause the elastic press-type buckles to fail to unlock or mislock, thereby separating the male and female ends of the connector, resulting in connection failure, causing server bandwidth loss or even downtime and other failure abnormalities, resulting in increased operation and maintenance costs, the utility model provides a cable connector structure.

[0006] The utility model is realized through the following technical solutions:

[0007] A cable connector structure, comprising:

[0008] The board-end connector has two limiting holes;

[0009] A wire end connector having two oppositely disposed positioning posts;

[0010] Two clamping arms are respectively rotatably connected to the two positioning posts, and one end of each clamping arm close to the board-end connector is provided with a clamping block capable of engaging with the limiting hole for positioning;

[0011] A spring, elastically supported on the clamping arm, exerting an elastic force on the clamping block to move toward the limiting hole;

[0012] The movable plate is slidably mounted on the line end connector and can rotate the clamping arm to move the clamping block away from the limiting hole.

[0013] A further improvement of the present invention is that the two limiting holes are arranged relative to the opening.

[0014] A further improvement of the present invention is that the movable plate is provided with a push block; the ends of the two clamping arms, away from the clamping block, are provided with bent portions that are bent relative to each other; and the sides of the bent portions, close to the clamping block, are designed to be inclined surfaces that can push and cooperate with the push block. When the movable plate is pulled upward, the push block will simultaneously abut the inclined surfaces of the two bent portions. As the movable plate continues to be pulled upward, the two bent portions gradually separate, and the clamping block is released from the limiting hole, thereby unlocking the line-end connector and the board-end connector, thereby achieving convenient separation between the two.

[0015] A further improvement of the present invention is that the two edges of the push block away from the board end connector are chamfered. The chamfers on the push block cooperate with the inclined surfaces on the bent portion to achieve smooth separation of the two bent portions to avoid jamming.

[0016] A further improvement of the present invention is that spring positioning protrusions are provided on the opposing inner sides of the two clamping arms for positioning the spring, and the spring positioning protrusions are disposed between the positioning column and the clamping block. The springs elastically support the two clamping arms below the positioning column, effectively ensuring the reliable engagement of the clamping block at the lower end of the clamping arms with the limiting hole. The two ends of the spring are positioned by inserting the spring positioning protrusions, ensuring the reliability of the spring's expansion and contraction process and preventing the spring from tilting or deflecting.

[0017] A further improvement of the present invention is that sliders are provided on both sides of the movable plate, and the line end connector is provided with a slide groove that cooperates with the slide guide to slide, thereby providing reliable sliding guide for the movable plate.

[0018] A further improvement of the present invention is that a positioning hole is provided on the clamping arm to rotatably cooperate with the positioning post, and the end of the positioning hole is chamfered to serve as a guide during assembly.

[0019] A further improvement of the present invention is that a drawstring capable of pulling the movable plate is connected to a side of the movable plate away from the plate end connector, so that a convenient pulling operation of the movable plate can be achieved through the drawstring.

[0020] A further improvement of the present invention is that a drawstring connecting post is provided on the side of the movable plate away from the plate end connector, and the drawstring is made of rubber and can be detachably connected to the drawstring connecting post, thereby achieving convenient, flexible and reusable detachable drawstrings.

[0021] A further improvement of the present invention is that the movable plate is provided with a groove which cooperates with the sliding guide of the end of the positioning column, thereby achieving reliability of the sliding guide of the movable plate.

[0022] It can be seen from the above technical solutions that the beneficial effects of the present invention are:

[0023] When the gold finger of the line-end connector is inserted into the gold finger slot of the board-end connector, the spring elastically supports the clamping arm, and the clamping blocks on the left and right sides are engaged with the limiting holes on both sides, ensuring the reliable and stable connection between the line-end connector and the board-end connector; when the line-end connector needs to be separated from the board-end connector, the movable plate is pulled upward, and the movable plate rotates the clamping arm to disengage the clamping block from the limiting hole and completely unlock it, so that the line-end connector can be easily pulled out upward, which is simple and convenient to operate. This cable connector structure has a simple overall structure and a left and right two-way clamping design to ensure the reliability of the clamping connection between the line-end connector and the board-end connector, effectively reducing the probability of abnormalities in the server during various manual wiring pulling and assembly processes, making wiring more convenient, realizing standardized wiring, saving space, and convenient unlocking operation, with good practicality. It will greatly improve the stability of the server during transportation, hot and cold shock machines, and various environmental tests, reduce the probability of defects, improve product stability, reduce operating and maintenance costs, and improve server quality.

DETAILED DESCRIPTION

[0031] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the specific embodiments. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this patent.

[0032] like Figure 1-5 As shown, the utility model discloses a cable connector structure, including two clamping arms 4, a spring 6, a movable plate 3, a line end connector 2 and a board end connector 1 that can be plugged in and out. The front side of the gold finger slot of the board end connector 1 is provided with two left and right limit blocks 11, and a limit hole 12 is provided on the limit block 11;

[0033] The front side of the line end connector 2 is provided with two cylindrical positioning posts 5 arranged opposite to each other on the left and right sides;

[0034] The two clamping arms 4 are rotatably connected to the two positioning posts 5 respectively, and a clamping block 41 capable of engaging with the limiting hole 12 for positioning is provided at one end (lower end) of the clamping arm 4 close to the board-end connector 1;

[0035] The spring 6 is elastically supported on the clamping arm 4 and has an elastic force on the clamping block 41 to move toward the limiting hole 12;

[0036] The movable plate 3 is vertically slidably mounted on the front side of the line end connector 2 and is capable of rotating the clamping arm 4 to move the clamping block 41 away from the limiting hole 12 .

[0037] When the gold finger of the line-end connector 2 is inserted into the gold finger slot of the board-end connector 1, the spring 6 elastically supports the clamping arm 4, and the clamping blocks 41 on the left and right sides are engaged with the limiting holes 12 on both sides, ensuring the reliable and stable connection between the line-end connector 2 and the board-end connector 1; when it is necessary to separate the line-end connector 2 from the board-end connector 1, the movable plate 3 is pulled upward (away from the board-end connector 1), and the movable plate 3 rotates the clamping arm 4 to disengage the clamping block 41 from the limiting hole 12, completely unlocking it, so that the line-end connector 2 can be easily pulled out upward, which is simple and convenient to operate. This cable connector structure has a simple overall structure, ensures the reliability of the clamping connection between the line-end connector 2 and the board-end connector 1, and the left and right bidirectional clamping design avoids problems such as connection failure caused by single-direction pressing, squeezing and vibration, thereby avoiding increased operation and maintenance costs. The unlocking operation is convenient and practical.

[0038] Among them, such as Figure 3-5 As shown, the two limiting holes 12 are arranged to be relatively open, that is, the two limiting holes 12 are open inward, and the two clamping blocks 41 are convex outward at the lower end of the clamping arm 4. The structure is simple and easy to implement.

[0039] like Figure 3-4 As shown, the central portion of the arm 4 has a positioning hole 42 that rotatably engages the positioning post 5. The end of the positioning hole 42 near the wire-end connector 2 is chamfered, and the end of the positioning post 5 is also chamfered. The rotatable insertion and engagement of the positioning post 5 with the positioning hole 42 ensures reliable rotation of the arm 4. The chamfered corners effectively guide assembly, making it easier to do so.

[0040] Further, such as Figure 3-4 As shown, spring positioning protrusions 43 for positioning and installing the spring 6 are provided on the opposing inner sides of the two clamping arms 4. These spring positioning protrusions 43 are located between the positioning column 5 and the blocking block 41 (i.e., below the positioning hole 42). The springs 6 elastically support the two clamping arms 4 below the positioning column 5, effectively ensuring the reliable engagement of the blocking block 41 at the lower end of the clamping arms 4 with the limiting hole 12. The spring 6's two ends are inserted and positioned by the spring positioning protrusions 43, ensuring the reliability of the spring 6's expansion and contraction process and preventing the spring 6 from tilting or deflecting.

[0041] Among them, such as Figure 3 、 4As shown, a push block 32 is provided in the middle of the rear side of the movable plate 3; the ends (upper ends) of the two clamping arms 4, away from the clamping block 41, are provided with relatively bent (inwardly bent) bent portions 44; the side (lower side) of the bent portions 44, close to the clamping block 41, is designed to be pushed and engaged by the push block 32, with the inclined surfaces sloping upward from the outside to the inside. When the movable plate 3 is pulled upward, the push block 32 will simultaneously abut the inclined surfaces of the two bent portions 44. As the movable plate 3 continues to be pulled upward, the two bent portions 44 gradually separate (i.e., the two clamping arms 4 rotate), and the clamping block 41 is released from the retaining hole 12, thereby unlocking the line-end connector 2 and the board-end connector 1, thereby conveniently separating the two.

[0042] Furthermore, the left and right edges of the push block 32 away from the board-end connector 1 (the upper side) are chamfered. The chamfers on the push block 32 cooperate with the inclined surfaces on the bent portion 44 to achieve smooth separation of the two bent portions 44 to avoid jamming.

[0043] like Figure 4 As shown, the outer edge of the lower end of the card block 41 is chamfered, and the whole forms a right-angled triangle structure. During the process of the line-end connector 2 and the board-end connector 1, the chamfered surface of the outer edge of the lower end of the card block 41 can realize the automatic inward pressing of the card block 41, without the need for unnecessary manual operation, thereby realizing the convenience of plugging the line-end connector 2 and the board-end connector 1.

[0044] Furthermore, chamfers are provided on the front and rear edges of the lower end of the clamping block 41 to serve as a guide during insertion.

[0045] like Figure 4 As shown, the movable plate 3 is provided with rearwardly protruding side panels on its left and right sides, with sliders 33 disposed on the outer sides of the side panels. The line end connector 2 is provided with a slide groove 21 that cooperates with the vertical sliding guide of the sliders 33. The provision of the side panels effectively limits the maximum rotation angle of the clamping arm 4, ensuring that the distance between the two bent portions 44 is less than the width of the push block 32, preventing the movable plate 3 from dislodging upward and ensuring the reliability of the vertical sliding fit of the movable plate 3 on the line end connector 2.

[0046] In order to improve the reliability of the vertical sliding guide cooperation between the movable plate 3 and the line end connector 2, the movable plate 3 is provided with a groove in the up and down direction for slidingly guiding the end of the positioning column 5.

[0047] like Figure 1-2 As shown, in order to facilitate the operation of pulling the movable plate 3 upward, a pull belt 7 capable of pulling the movable plate 3 is connected to the side of the movable plate 3 away from the board-end connector 1 .

[0048] Furthermore, a drawstring connecting post 31 is provided on the side of the movable plate 3 away from the plate-end connector 1, and the drawstring 7 is made of rubber and can be detachably connected to the drawstring connecting post 31. The drawstring 7 is easy to assemble and disassemble and can be flexibly reused.

[0049] In this cable connector structure, when the gold finger of the line-end connector 2 is inserted into the gold finger slot of the board-end connector 1, the spring 6 elastically supports the clamping arm 4, and the clamping blocks 41 on the left and right sides are engaged with the limiting holes 12 on both sides, ensuring the reliable and stable connection between the line-end connector 2 and the board-end connector 1; when it is necessary to separate the line-end connector 2 from the board-end connector 1, the movable plate 3 is pulled upward (away from the board-end connector 1), and the movable plate 3 rotates the clamping arm 4 to disengage the clamping block 41 from the limiting hole 12, completely unlocking it, so that the line-end connector 2 can be easily pulled out upward, which is simple and convenient to operate. This cable connector structure has a simple overall structure and a left and right two-way clamping design, which ensures the reliability of the clamping connection between the line-end connector 2 and the board-end connector 1, effectively avoiding the failure of the press-type clamp to unlock or mis-lock due to manual cable management, wire stacking and squeezing, etc., thereby avoiding increased operation and maintenance costs. The unlocking operation is convenient and practical.
